Range DescriptionAotus vociferans occurs north of the Rio Amazonas-Solomes, west from the Rio Negro. It occurs south of the Rio Solimes in a small incursion either side of the mouth and lowermost reaches of the Rio Purus. West it extends into Peru north of the Ro Amazonas and Maran, not extending it would seem right to the Rio Maran, with a narrow belt along the north of the river being occupied by A. nancymaae (Aquino and Encarnacin 1994a). It extends north through the Ecuadorian Amazon into Colombia to the Ro Guaviare, probably extending east as far the ros Negro, Atabapo and Orinoco (Hernndez-Camacho and Cooper 1976; Defler 2003, 2004).
